Patented Mar. 25, 1930 PATENT OFFICE BENJAMIN VEENSTR-A, OIE HAWTHORNE, NEW JERSEY W'A'IIElR-FLOW DEVICE Application filed May 10, 1928.

This invention relates to liquid-fiow devices designed primarily for use in connection with the operations of dyeing piecegoods of silk or other material, although the .5 same may be used in connection with operations in paper-making or for other purposes.

In the operation of dyeing piece-goods of silk or the like, there is frequent occasion to 1 Wash out the goods duringor after application of the dye. Such washing of the goods, if in fiat form, is done by subjecting the fiat goods to the action of one or more spray-devices; and, when the goods, are in rope form, by

immersing them into a vessel containing Water. But spraying-devices deliver the water as a spray, or plurality of individual ets; and these individual jets of water are quite liable to produce on the goods local discoloration or blurs, many of which will remain permanently and cannot be removed. When the goods in rope form are immersed into a vessel of fresh water, the water at once begins to be contaminated, and, moreover,

755 there is liability of blurring the color of the goods.

The object of my present invention is to produce an efiective yet inexpensive flow-device by which a continuous and uninterrupted 39 sheet of fresh water-in contradistinction to a plurality of individual jets, and to a body of (still) water in a receptacle-can be applied at willto the goods, whether the latter be in flat form or in rope form.

Broadly stated, the gist of the invention consists of the combination of (l) a pipe that receives a flow of water from any suitable source and discharges the same in individual jets through a plurality of. apertures, and

(2) means for breaking-up and diffusing Serial No. 276,557.

Other objects and advantages of the present invention will be set forth below, or will be obvious in view of the ensuing detailed description of preferred embodiments of the invention.

The invention will be best understood from the ensuing description of a preferred embodiment thereof, in connection with the accompanying drawings. These drawings are merely illustrative, in aid of the ensuing description; and the ensuing description itself is merely illustrative of the invention, and is not intended to limit the scope of the present invention, which will be defined in the appended claims.

In the accompanying drawings, Fig. 1 is a longitudinal sectional view of a preferred longitudinal form of the new liquid-flow device embodying the invention;

Fig. 2 is a transverse section through the device of Fig. 1;

Fig. 8 is a face View (partly in section), on a smaller scale, of a preferred circular or doughnut form of the new flow-device, the upper half-portion of the outer member being removed; and

Fig. t is a transverse section through the complete device of Fig. 3.

Referring to these drawings, 4: is an openended pipe, screw-threaded at each end. 5 is a continuous slot therein, which extends along one side of said pipe, and terminates a short distance from each end thereof. 6 is a centrally-apertured reduction-coupling that is threaded upon one end of pipe t and he. a circular screw-threaded hole, which is here shown as concentric with the member 6; and 7 is a similar reduction-coupling threaded upon the other end of said pipe and having a similar screwthreadod central hole. 8 is a smaller open-ended pipe, externally screwthreaded on each end for engaging the threads around said holes of said couplingmembers 6 and 7. These members 6 and 7 maintain the inner pipe 8 in fixed position, here shown as concentric, within the outer pipe 4:, and serve to close the ends of the space between the two pipes. It is within this enclosed space that the individual water jets are broken up and diffused. 9 is an inlet-nozzle at one endof the inner pipe 8; and 10 indicates a coupling for a valve-controlled water pipe. (not shown). 11 is a removable plug that is screw-threaded into the opposite end of the inner pipe 8; 12-12, etc., represent a plurality of small apertures space-d apart along the length of the inner pipe 8, and all discharging away from the aforesaid slot 5. Preferably, these apertures are aligned rectilinearly, and are located diametrically opposite the slot 5.

in a device designed and successfully used for washing piece-goo'ds, the slot 5 is about of an inch wide; the apertures 12 are of an inch apart; and half of thenn'those nearer the inlet 9, are 5% of an inch in diameter, and the rest of-them (those nearer the closureplug 11) are smaller, or A; ofan inch in diameter, in that particular device, designed for washing piece-goods 48 inches wide, the slot 5 is 48 inches long, and the outer pipe 4 eX- tends about three inches at each end beyond the slot 5,'so that the outer pipe is about 5d inches long; and the internal diameter of the inner pipe is 7 of an inch, of the outer pipe is 1 inches The apertures 12 might be regularly graduated in diameter, the one nearest to the inlet being the largest and those successively nearer the plug closure 11 being successively smaller, but in practice it has been found sufficient to have the first half of the apertures 12 of the same uniform larger diameter (say of an inch) and the remainingapertures of the same uniform smaller diameter (say of an inch). By practical tests it has been demonstrated that each of the two arrangements just set forth,'wherein apertures of larger diameter are nearer the If desired, for the purpose of protecting the piece-goodsfthe outer pipe 4: may be covered with a shell 13, wh ch maybe of hard rubber or other compos tion, or may be otherwise covered, the slot 5b ing of course leftfree.

r The manner of using the new flow-device of Fi s. 1 and 2 and its mode of o aeration will r 4 0 now be obvious. The device is mounted in convenient location, usually a pair of -thein parallel and in horizontal position, where V the piece-goods canbe drawnlin fiat form between the two devices, which areso disposed that the slot 5 of the upper one will discharge downward, and the corresponding slot of the lower device will discharge upward. "The water-from the supply-pipewill be admitted,

under the desired pressure and in the desired amount ,(by means of the control-valve, not

7 shown), through the nozzle 9 and into the in ner pipe 8.' Individual jets of water will be discharged from the inner pipe against the curved inner face of the outer pipe 4; but these individual jets will be broken up and difiused,and the body of water within the enclosed space between the pipes will be discharged through the slot 5, and against fiat goods, as a uniform and uninterrupted sheet two half-portions that are identical, so that only one of them requires particular description. The lower half-portion seen in Fig. 3, consists of a flat annular outer flan e-portion 1a andan inner annular trough-portion 15, the inner lip 16 of the latter lying inthe plane of the flat upper surfaceof the flange; 14, If the two halfportions should be, placed together, the inner lips 16 of the two halfportions would lie in closecontact with each other.v However, beforeassembling the parts,

gasket 17, ofrubber or the like, is to beinterposed between the two flangesltwhich are then secured together as by bolts or the like, thus providing a continuous. and uninterruptedslot between the two lips 16., There is an inner pipe 18 of circular fornnlocated within the trough 15, and supported :by a hollow stem 19 whichis brazed or otherwiseconn cted to one of the two complementarysernicylindrical grooves (notshown) in the ref spective half-portions aforesaid. Then said gasket 17 is placedin position upon iiange 14; the upper half-portion of the. outer ringis then inverted audits flange seated upon said} gasket, and r the two j flanges secured; together to clamp the gasket, The outer endof said hollow stem 19, as with the aforesaid inner; pipe" 8 in Fig; 1, isthen connectedwith a ee led waterip re v(net o so as to conduct water into'the circularmember 8- The re tures tl e n r mem r are as already described with reference to thedevice of Figs. 1 a'nd2, all discharging away from the slot at 16,'and,preferably discharging in a direction radially (diametrically) op-.

posite to said slot. The piece-goods, inrope form, will be passed throughtheeye of the ring-like device of Fig. 8, passing pref'erably in vertical direction through the horizontallydisposed eye of the devicewhich discharges, in radially-inward directions, and against the entire circumference of the rope form, an

uninterrupted sheet ofwa er of disklike or annular shape. 7,

fiat form, e. g., for washing paper in the paper-making industry.

Figs. 1 and 2 indicate that each of the pipes 4 and 8 is straight, and in cross-section is circular, and that the two pipes are arranged concentrically. In Fig. 3, the two hollow members (1415 and 18 respectively) are indicated as rings, and as arranged concentrically; moreover, the transverse section seen in Fig. 4 shows that the circles 15 and 18 (representing cross-sections of the two hollow rings) are likewise arranged concentrically. In the device of Figs. 1 and 2, the apertures 12 are aligned rectilinearly, and are located diametrically opposite to the slot 5; and in the device of Figs. 3 and 4, the apertures are arranged around the ring 18 in the same plane as, and diametrically (that is, directly) opposite to, the slot at 16. All these details are preferable. Nevertheless, these hollow members, whether straight or rings, need not be of circular cross-section, nor need each pair of hollow members be arranged concentrically, nor need the apertures of the inner member (of either shape) be aligned rectilinearly or otherwise, provided always that these apertures do not discharge directly into the slot, and provided always that there be suflicient enclosed space for the individual water-jets to be broken up and diffused so as to discharge water from the slot as a sheet.

In the ensuing claims, the word pipe is to be understood as referring to a ring-like hollow member as well as to a straight hollow member, and to a hollow member that is noncircular in cross-section as well as to one that is circular.

It is also to be understood that the ensuing claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
